> If that's the case, then the landlords could save the money they're spending on YieldStar and just set the high prices already. They could use their own proprietary "I want more money" algorithm, and the tenant would have no choice but to pay whatever number the landlord popped out of their head. Now you're getting it. They could do this, but if their number is higher than other owner numbers in their area, they lose. If it's the same as other numbers in their area, they win. So they need something to coordinate those numbers. A 3rd party, for example. And thus we arrive at why people call it collusion via a 3rd party.
